Abstract

PURPOSE:To input/output an output value without passing through a central processing unit and to shorten the processing time of the central processing unit. CONSTITUTION:Data which are simultaneously inputted to input devices 3 and 4 are converted into data of a system, which can be processed in the central processing unit 1 by data processors 7 and they are outputted to a storage device 2. The data processors 7 read neccessary data from an auxiliary storage device 8 based on inputted data and outputs it to the storage device 2 according to circumstances. The central processing unit 1 inputs data from the storage device 2 in asynchronizing with output devices 5 and 6, executes a necessary processing and outputs output data which the output devices designate to a part storing output data in the storage device 2. The data processors 7 controlling the output devices 5 and 6 select data required for output from data stored in the storage device 2, and the respective output devices convert it into data of the system which can be outputted. Then, data are outputted to the output devices 5 and 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing terminal device, and more particularly to a data processing terminal device which requires various types of input / output devices.

[0002]

2. Description of the Related Art When a conventional data processing terminal device has various kinds of input / output devices, all input devices and output devices are controlled in a central processing unit. The central processing unit reads the input data from one of the input devices that have received the input, performs the necessary processing, and then outputs the data to the output device.

[0003]

In the above-described conventional data processing terminal device, when there are inputs to a plurality of input devices at the same time, the central processing unit processes only one data, so that the data of other input devices are not processed. It is not processed and it is difficult to input at high speed. Further, since the data format differs depending on the input device, the central processing unit needs to convert the data into processable data, which requires a complicated process.

[0004]

A data processing terminal device of the present invention includes a plurality of types of input devices including a keyboard, a scanner for reading a bar code attached to a product, and a card reading device for reading a magnetic card, and a screen. A plurality of types of output devices including a display device and a printing device are provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. The data simultaneously input to the input devices 3 and 4 are converted by the respective data processing devices 7 into data in a format that can be processed by the central processing unit 1 and output to the storage device 2. In some cases, the data processing device 7 reads necessary data from the auxiliary storage device 8 based on the input data, and then outputs it to the storage device 2. The central processing unit 1 is a part for inputting data from the storage device 2 asynchronously with the input devices 3, 4, and output devices 5, 6 and for storing the output data in the storage device 2 after performing necessary processing. The output data for which the output device is specified is output to. The data processing device 7 that controls the output devices 5 and 6 selects the data required for output from the data stored in the storage device 2, and after converting the data into a format that can be output by each output device. , Output data to the output devices 5 and 6.

[0007]

As described above, according to the present invention, by providing the input / output device with the processing device, it is possible to input / output data without going through the central processing unit. Since the processing device of (1) converts the data into data of a format processed by the central processing device, the processing time of the central processing device can be shortened.
